TypeScript
A typed superset of JavaScript that adds static type checking and improved tooling to the language.
Why it matters
- Catches errors at compile time before they reach production
- Improves code documentation and IDE support
- Makes refactoring safer and more confident
When to use
- For any non-trivial JavaScript project
- When working with large teams or codebases
- When code maintainability is a priority
Common mistakes
- Using 'any' type everywhere, defeating the purpose
- Over-engineering types when simple ones would work
- Not leveraging IDE features that TypeScript enables
